WASHINGTON (Reuters) - The Pentagon was gripped by an Ebola scare on Friday after a woman vomited in a parking lot, triggering authorities to send in a HazMat team and shut off part of the military complex before concluding she did not have the deadly virus.The Pentagon initially said in a statement that the woman indicated she had "recently visited Africa."But her employer told Reuters she had not traveled abroad recently and local county health authorities later acknowledged that her travel history had been uncertain.
